> When the destination datanode gets the checksum mismatch, it reports bad
> block to NameNode and NameNode marks the replica on the source datanode as
> corrupt. But actually, the replica on the source datanode is valid. Because
> the replica can pass the checksum verification.
> In all, the replica on the source data is wrongly marked as corrupted.
